A hot gas duct doesn't fail all at once. It starts as a hairline crack in the refractory lining, quietly lets heat reach the steel shell, and months later turns into an unplanned shutdown that costs a week of production. Sign up to see how Oxmaint tracks duct and refractory condition before it becomes an emergency repair.
Rotating equipment gets vibration monitors and oil analysis because it's easy to picture a bearing failing. Ductwork and refractory lining sit still and hidden inside insulation, so damage builds silently until a shell hot spot or a stuck expansion joint forces an unplanned stop. The fix isn't more inspections, it's the right inspections at the right interval.
Three Zones, Three Failure Patterns
Oxmaint logs shell temperature readings against a fixed baseline for every monitoring point, so a slow rise gets flagged as a work order instead of getting lost in a logbook. Sign up for a free trial to set up your duct monitoring points, or book a demo and we'll walk through your refractory inspection plan.
Reactive Repairs vs Condition-Based Monitoring
Refractory relining happens as an emergency, not a planned outage
Expansion joints are replaced only after visible gas leakage
Relining is scheduled into the next planned shutdown window
Expansion joints get replaced on a fatigue-cycle schedule, not by surprise
Oxmaint turns shell temperature checks, expansion joint inspections, and refractory thickness readings into scheduled work orders tied to each monitoring point. When a reading drifts past its baseline, the system flags it automatically instead of waiting for the next scheduled shutdown to find out. Book a demo to see your duct and refractory data organized into one dashboard.
